TAPPEN TOWNSEND, OF ALBANY, NEW YORK.

WARMING RAILROAD-CARS.

Specification of Letters Patent No. 4,654, dated July 24,y 1846.

To all whom t may concern:

Be it known that I, TAPPEN TowNsEND, of the city and county of Albany,and State of New York, have invented anew and Improved Mode of Warmingthe Interior of Railroad Passenger-Cars; and I do hereby decla-re thatthe following is a full and exact description.

The nature of my invention consists in providing railroad trains oflocomotives and cars with apparatus for generating, and distributingheater air, warmed by the fire of the locomotive, to the interior ofeach passenger car.

To enable others skilled in the art to make and use my inventio-n, Iwill proceed to describe its construction and operation.

Through the furnaces of any of the known forms used in locomotives, Ipass one or more cast iron pipes, which presenting enlarged orifices tothe open air in front as shown at A, in the acco-mpanying drawings,pass, and if necessary repass, and pass again through the heatingelement at B, and thence communicate backward with a reservoir situatedin the platform upon which the fireman stands, and marked C in thedrawing. From thence I receive the heated air by means of the elasticand iiexible hose marked lD, into a continuous trough or air chamber,which I let into the sleepers of each car as seen at E,-the flexible andelastic hose being constructed by inclosing a spiral coil of wire inmetallic india rubber, that will resist, two hundred and fifty degreesof heat without melting, and which never becomes stiffened with thecold, using for the purpose of protecting the rubber Holland duck on theinside, and well tanned horsehide on the outside, or any other materialsthat will answer the purpose,-the Holland duck to be prepared inasolution of alum, and both the duck` and horsehide, to be madesufficiently longer than the rubber and spiral coil of wire to accommodate the elasticity of both. I connect these elastic and flexiblehose to the air chambers or troughs by means of metallic coupling screwsor otherwise; the coupling screws marked F, in the drawing. I thusconvey the vheated air from the reservoir C', through the train, andadmit the same into the passenger cars, by registers G. Each car isfurnished with two registers to accommodate the running ofthe carseither backward or forward, and each opening at the extremities of thecontinuous air chambers are furnished with metallic cap screws (markedH, in the drawing) to be screwed on to theorifices duringsummer and alsoto close the two orifices in the extreme, or termination o-f thepassenger train in winter.

In the drawings Figure l is a front per-V spective view of the rear halfof the engine in which the furnace is located; and Fig. 2, a rear viewof the same showing the position in which the cast iron pipes will beplaced.

Fig. 3, a ground view of the whole train, in which, c, is the furnaceand pipes as in Figs. l and 2; ZJ, the tender, c, a baggage car, and d,d, the passenger cars. Fig. 4L the frame work of the floor of apassenger car, into which is inserted the air troughs or chambers, Erepresenting the momentum retainer. Fig. 5, the end of the air trough orchamber, with the elastic and iexible hose D, being an external andcomplete view,

with a section of the coupling screw F, attached, and f, the spiral coilof wire within. Fig. 6, an enlarged View o-f the two parts of thecoupling. Fig. 7 is the metallic cap screw.

What I claim as my invention, and desire to secure by Let-ters Patentis- The application to rail road passenger trains, of the combination ofthe flues connected, by the elastic and flexible hose with the openingsand registers in the bottoms of the cars, as described herein, referencebeing also had to the accompanying drawings.
